A Search for Isotope Effects in Chemiluminescent Reactions of Metastable Ca*( ³Pj, ¹D₂ ) Atoms with CH₃I and CD₃I Molecules

Abstract

Chemiluminescent reactions of calcium atoms in the metastable Pj and 'D, states with CH 3 I and CD 3 I were studied in a beam-gas arrangement. Calcium monoiodide spectra associated with transitions from the electronic A IT, B 2 Z + and C 2 n states to the X 2 L + ground state were recorded. Total collision and chemiluminescence cross sections were measured. It was found that isotopic substitution in the methyl group does not change the reaction cross sections and the chemiluminescence spectra.
